​​​​Payment service providers (PSPs) who require a GB International Bank Account Number (IBAN) but have no need to offer payments to their customers via the UK payment systems, can either:

  1. Approach a direct participant of one of the payment schemes to request a sort code

  2. Contact Bacs to request a non-standard sort code(s) – see 'Process for allocating a non-standard sort code' below for more details.

Terms of Use - NB This non-standard sort code will be issued on the basis it cannot be used in any of the UK payment systems. Cheques cannot be issued on this type of sort code nor are these sort codes currently listed in the Extended Industry Sort Code Directory (EISCD), so they cannot be validated against that database.

The following institution types are eligible to obtain a non-standard sort code for use with an IBAN:

  • Authorised payment institutions
  • Small payment institutions
  • European Economic Area (EEA) authorised payment institutions
  • Credit institutions
  • Electronic money institutions
  • The Post Office Limited
  • The Bank of England, the European Central Bank and the national central banks of EEA states other than the United Kingdom
  • Government departments and local authorities.

Process for allocating a non-standard sort code

  1. PSPs should contact Bacs via the 'Contact us' page
  2. Subject to validation of the institution type, Bacs will require completion of the Non-Standard Sort Codes Questionnaire​, asking the applicant to provide details/reason for requiring the non-standard sort code
  3. Once the questionnaire is completed and returned, Bacs will determine next steps
  4. If the request relates to making SEPA payments to UK customers, the applicant must also comply with the SEPA regulation and register as a UK SEPA adherent.  In addition, they may also need to participate in the SEPA IBAN-Only Directory to help meet their UK reachability requirements.
  5. The National Adherence Support Organisation (NASO) and SEPA IBAN-Only representatives within Payments UK will also need to review the questionnaire and may arrange a short audio call to discuss the SEPA regulations
  6. The review by Bacs and PUK will determine if a non-standard sort code will be issued
  7. The decision will be communicated to the applicant and if successful the sort code will be issued within one working week subject to confirmation of the terms of use
